Stripping of VOC

Stripping of Volatile Organic Compounds From Refinery Waste Water

Stripping of Volatile Organic CompoundsThe major purpose of this writing is to provide a quick but reasonably accurate method for sizing a stripper to reduce the concentration of a volatile organic compound (VOC) in a typical refinery waste water stream down to some specified or acceptable level.  The procedure presented here employs a simple BASIC computer program to compute the number of theoretical stages using Kremser’s equation.  Then certain correlations and methods are used to determine stripper diameter for cases where sieve trays are to be used and also cases where random packing might be considered.  The actual number of trays (sieves) or height of packing needed are determined by applying an appropriate tray efficiency or recommended HETP (height equivalent to a theoretical plate).
